Knicks F Kristaps Porzingis has been ruled out for Saturday night's game against the Thunder with a knee injury, according to the team.
Michael Beasley will start in place of Porzingis and Joakim Noah will be active.
Porzingis was testing his knee and talking to doctors during warmups, according to the Knicks, but is unable to return to the lineup.
As of Friday, Porzingis was ruled day-to-day due to a sore left knee and was questionable for Saturday's game against Carmelo Anthony and the Thunder.
Porzingis had been set to undergo further tests on his knee after he left Thursday's win over the Nets early after a non-contact injury that had him feel "a little shock pain."
Porzingis said he didn't think the injury was severe and said he was removed for precautionary reasons after his knee buckled while defending a Rondae Hollis-Jefferson drive.
"I felt my knee buckle a little bit and I felt a little pain there. So it's more about being cautious," Porzingis said after the game, according to ESPN's Ian Begley. "I had a little shock pain there and that's it. I honestly don't have any information about what's going on there, but hopefully it's not too serious."
Porzingis scored 13 points and recorded four assists in 18 minutes prior to leaving Friday's game.
